About T69.02

T69.02 is the ICD-10-CM diagnosis code for Immersion foot. It belongs to category T69 (other effects of reduced temperature), block T66-T78 (other and unspecified effects of external causes) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T69.0 (Immersion hand and foot), T69.02 is specifically for Immersion foot. Related codes cover hand (T69.01).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional code to identify source of exposure: Exposure to excessive cold of man-made origin (W93) and Exposure to excessive cold of natural origin (X31).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
